file_column error: StringIO Instead of Temp_File
...oad.
The problem is when i try to upload a file (or 2, or 3) sometimes it
works, but sometimes i get this in the log file:
"bar_image"=>{"file_temp"=>"", "file"=>#<StringIO:0xb4b08268>}
and the picture is not saved.
the pictures i upload are 60x60 and there is no file_column validations
or limitations at all.
when uploading larger images (500x500 for ex.) it works.
anyone?

comparing execition time: R vs matlab linear algebra...
...with most nonzero values near the main diagonal,
CURR is an n x 1 vector:
the MATALAB script:
P = G \ CURR; % matrix left-divide
QG = qr(G)
P = qr.coef(QG, CURR)
The answer we get matches that of the MATLAB code for small (60x60)
problems.
But, execution times are much longer (40 minutes, compared to 2 minutes for
the MATLAB script)
Also, the R version cannot accommodate a solution matrix greater than
aprox 10,000 x 10,000 elements,while the MATLAB script has generated
solutions for 10**6 x 10**6 solution matrices.
My q...

Pairwise comparison matrix elements
...ll out-of-the-box ideas I've come up with and tried haven't gotten me much farther. I've now practically exhausted my creative thinking, and I'm becoming very frustrated. I'd really like to get this script going since my current one would make my life hell for large populations (60x60 population matrices).
Any ideas on how I could move forward?
Many, many thanks!

Add an index to a form
Hello,
I''m having some trouble with forms, my app allows to enter data by
using a multi-step form that has 7 steps.
There are 3 steps that may let the user to add 1 form, for example
there''s a step called "children"
and that children has the following fields:
* name
* age
* gender
but one father may have more than 1 child and I''m adding another form
